Method for Transmitting and Receiving Control Information of a Mobile Communication System

2. The communication method of claim 1, wherein a slot number of the first time slot is of a first value, a slot number of the second time slot is of a second value different from the first value, and the slot number of the time slot in which the search space is located is used to determine the location of the search space.

4. The communication method of claim 3, wherein the first message comprises information on a starting Orthogonal Frequency Divisional Multiplexing (OFDM) symbol of the search space in the first subframe.

5. The communication method of claim 2, wherein the location of the search space for the control channel is determined using also a Cell-RNTI (C-RNTI) of the terminal.

8. The terminal of claim 7, wherein a slot number of the first time slot is of a first value, a slot number of the second time slot is of a second value different from the first value, and the slot number of the time slot in which the search space is located is used to determine the location of the search space.

10. The terminal of claim 9, wherein the first message comprises information on a starting Orthogonal Frequency Divisional Multiplexing (OFDM) symbol of the search space in the first subframe.

11. The terminal of claim 8, wherein the location of the search space for the control channel is determined using also a Cell-RNTI (C-RNTI) of the terminal.

14. The communication device of claim 13, wherein a slot number of the first time slot is of a first value, a slot number of the second time slot is of a second value different from the first value, and the slot number of the time slot in which the search space is located is used to determine the location of the search space.

16. The communication device of claim 15, wherein the first message comprises information on a starting Orthogonal Frequency Divisional Multiplexing (OFDM) symbol of the search space in the first subframe.

17. The communication device of claim 14, wherein the location of the search space for the control channel is determined using also a Cell-RNTI (C-RNTI) of the terminal.
